IMPROVEMENT IN TOBACCOY-SPIN NING MACHINES.

Specificati on forming part of Letters Patent No. 37,948, dated March 24, 1863.

To all whom it nmy concern:

Be it known that I, ERNsr BREUL, of Hanover, Kingdom of Hanover, have invented a new and useful Machine for Spinning Chewing-Tobaceo, and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 represents a top View of said machine for spinning and winding tobacco. Fig. 2 represents a side view of the same. Fig. 3 represents an end view.

My invention relates to the arrangement of a drum and the devices for operating the same within a spinning-frame, whereby I am enabled to spin and wind up the tobacco at one operation, thus saving the labor which heretofore was necessary for winding the tobacco in rolls after it was spun.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The spinning-frame consists of the forked part A, the end L serving as a hollow trunnion, which passes through ajournal-box, in which it revolves. The longitudinal bars B connect the part A with the cross-bar B, to which the shaft N isseeured in line with thetrunnion L, and which terminates in the trunnion H, as the other bearing on which the spinning-frame revolves. The pulley m is firmly secured to the shaft N, and constitutes the driving-pulley of the spinning-fran1e. A loose pulley, n, firmly secured to the pulley 0, turns loosely on the shaft N. The drum 1?, for receiving the twisted tobacco-threads, is mounted on the spinning-frame, and has its bearings at a a on said frame. The drum is composed of iron slats or strips 1), which are secured to the disk f by means of the bolts 0, and to the disk E by means of the thumb-screws 7L. The shaft D of the drum can be withdrawn from the frame when the tobacco on the drum is to be removed by first removing the pin 7;, by which the shaft is secured. The pulley p, by which the drum 1? is rotated, is set loosely on the sleeve 7.:, but is secured to the disk f of the drum P by means of a pin, 9, which enters the faces ofboth. The pulley S is permanently secured to the sleeve k, and by means of a belt or rope imparts a rotary motion to the pulley u of the screw-shaft w. The screw-shaftm has its hearings in the frame at F, and has a right and left thread cut on its circumference, into. which a steel edge, y, is pressed by means of a spring, q, both being secured to a sleeve, G, which can pass freely over the screw-shaft w.

' The sleeve G is, besides, hung on the rod Q,

to keep it in its proper position, and the arms T extend from the sleeve and support the guide-pulley F, overwhich the tobacco-thread passes to the drum P.

The operation of the machine is as follows: Motion is imparted to the spinning-frame by turning the pulley m by means of a crank, treadle, or other power, and the tobacco is fed through the hollow trunnion L and passes over the guide-pulley F. Motion is also given to the pulley n, which operates the pulleys 0 and e and causes the drum 1? to revolvewithin the revolving spinning-frame by the pulley 1) being driven from the pulley c. This causes the pulleys s and u, and consequently the screwshaft x, to rotate on their bearings. The tobacco is spun into threads by the rotary motion of spinning-frame, while it is fed through the hollow trunnion 'L. It then passes over the guide-pulley F, and thence to the drum- P, on which it is wound up spirally as the guide-pulley F is moved longitudinally at such a velocity as to lay the threads snugly 011 the rolls on the drum 1?. This velocity may be regulated by inserting a pulley, a, of the proper dimensions.

To remove the finished roll from the drum P the thumb-screws 71.3;16 unscrewed, the disk E is removed, and the stripsbyield sufficiently. to enable the operator to remove the roll of tobacco with facility. NVhen the sleeve G has arrived at the end of the screw-shaft, the steeledge clasp y is guided by the shape of the screw-thread into the reversed screw-thread, and thus carries the guide-roller and tobaccothread backward and winds layer after layer on the roll. The spring g, which presses the steel clasp against the screw-shaft, is hinged to the sleeve G, and may be turned so as to relieve the clasp, when the sleeve may be freely slid over the screw-shaft.

Having thus fully described the nature of my invention, what I claim herein as new, and desire to secure by Letters Patent, is-

1. In combination withthe revolving spinning-frarne, the revolving drum P, for spinning and winding tobacco, substantially in the manner and for the purposes set forth.

2. In combination with a spinning-frame} tially in the manner and for the purposes here in set forth. 1
